However, the effective area of the tube 22 is reduced at the hinge connections 33 of the plates 31 and 32 because of the approach of these hinge connections to the longitudinal axis of the pipe 22 and con- 'sequently the speed ot-the air at this point is increased, and, moreover, as it passes the point of close approach to the central portions of the plates 31 and 32 theair then expands with a resultant production of subatmospheric pressure-lower than would occur itthe pipe 22avere freely open throughout. There is, therefore, an injector action on the gasolene within the pipe and this gasolene is withdrawn "from the pipe through .the end of the pipe within the tube 22, and this gasolene is directed toward the plate42 to be deflected thereby into the streams'of air passing alongside of the plate '.42,"through.the sleeve .35, with the result that the gasolene is finely divided and at once evaporated and absorbed by theg'air, to

The relation betweenthe effective opening at the hinge portion 33 of the plates- .31 and 32 and the relation thereto of the valve 40; is variable by means of the screw 24; acting on the-sleeve 29 to move it longif'tudinally of the tube 22.

Difiiculty is found in starting explosion engines using gasolene as a fuel, especially certain flow of air occurs through the I in very cold weather, but in the practical operation of the present invention it is found that the engine is readily started in the coldest weather without priming. The carbureter of'the present. invention in its practical operation is very flexible and ,may be adjusted until throttled down so that the engine speed may be reduced to a low minimum, but when the carbureter is opened up the power generated by the engine is markedly superior due to the closeapproach to the ideal explosive mixture. The carbureter of thepresent invention has a sufficiently wide range of adjustmentto adapt. it to any cxplosionengi-ne, and when once adjusted to the engine no further change is necessary.
